Letters Patent No. 875,097, dated December 22, 1868.

mPRovEMENT IN WINDOW-FRAMES.

The Schedule referred to in 4these Letters Patent and making part ofthe same.

skilled in the art to make and use the same, reference;

being had to the accompanying drawings, forming part of this specification.

This invention relates to an improvement in the imethod of fastening th e stop or bead-casings which hold in the sashes of windows; and s.

It consists Ain the application of an eccentric-lever for that purpose, in combination with a pin in'the bead or stop-easing, and in the manner hereinafter more fully described. l l l Figure 1 represents .a sectional front inside elevation of the window with the eccentric applied, as when fastening the stop-casing.

Figure 2 is a detailed view of the fastening-deviceA on an enlarged scale,in order to show to -better advantage its constructionland operation.

Similar letters of reference indicate corresponding parts.

A A represent the upper and lower sashes of the window;

B is the face-casing of the window; and

C represents thestop or bead-casings by which' the sashes are held in their places.

D is the eccentric-lever. which may be attached to and have its pivot or fulcrum in a metallic frame, E, as seen in iig. 2, and the frame mortised into the jamb of the window, as seen at F, in fig. 1,'or it may be connected directly with the jamb-'casing or windowfframe by a simple pivot, as seen at G, iig. 1.

In either case a .mortise is made in the jamb tov receive the eccentric-levenandsuiioiently long vertically to allow the .eccentric the necessary play or movement up and down.

A mortise or slot` is made entirely through the beadcasing C, which is seen inthe drawing, fig. l, at y.

' Securely fixed in this mortise or slot there is a pin, i.

The pivot or fulcru-m ofthe eccentric-lever is marked' k. `Upon this point lo the eccentricelever turns.

kThe inner portion of the eccentric-lever forms a curved line,.drawn from its extreme point m, which line approaches the central pivot k, and terminates at a point near the central pivot, so that when the eccentric is drawn down over thepin i, the tendency Yis to draw the pin and the bead-casing towards the central pivot k, and consequently to press the beadcasing against the jamb of the window, with any force which may be required to keep it in place.

The slot g, through the bead or stop-casing, may be {bri-)ad enough to'allow the bead to be moved or crowded y .against the sash,to keep the sash tight, or to prevent its= rattling. A i A lo remove the bead-casing from the window, for taking out lthe sashes, it is only' necessary to vraise the eccentric bythe projecting end n, which turns i-t back into the mortise, thereby releasing the pin i, and

the casing'or bead, which is then readily removed.

This is but a nmments work and the arran ement avoids the necessity of using nails or screws, and thus injuring and defacing lthe bead.

One or more of the eccentrics may be used to a bead, as may be deemed necessary, either with or without the frame E.

The form of the eccentric may be somewhat varied, and the same or a similar result be produced.

We do not therefore confine ourselves to the particular form of the eccentric' taken as a whole, but propose to use any' form of lever, whereby an increasing pressure on the bead-casing is produced by an eccentric movement.

Neither do we limit ourselves tothe particular arrangement shown in the drawing.

The 'eccentric might be attached to the bead-casing. and the pin i placed in the jamb, but we prefer the method shown and described.

The advantages of'this method of fastening aremany and obvious, and must be appreciated by all who have been annoyed with rattling windows, or have been troubled in taking oio the stop-casing for removing the sashes, forwashing, glazing, or other`purposes.

We claim as new, andrdesire to secure by Lettels Patent- 1. The eccentric-leversD, pivoted within the case E, or withinthe window-jamb at Gr, and adapted to lit over the pin t in the slot g of the stop or bead, all operatingV as described, whereby the depression of the lever draws the bead firmly within the casing, as herein `shown and described, for the purpose specified.

2. The combination of the. eccentric-lever D and pin i with the window-casing and the slotted bead C, whereby an increasing pressure is produced by the eccentric movement of the lever, substantially as described, for the purpose speciiied.-
